APPARATUS FOR MAKING AND BURNING GASOUS FUEL.

SFECELTICATION forming part of Letters Patent No. 330,190, dated .November 10, 1885.

l Application filed J'une 6, 1885. Serial No. 167,818. (No model.)

Fuel, of which the following is a specifica tion.

This invention relates to the apparatus for making and burning gaseous fuel shown in the application of It. I. Ambler (one of the present applicants) for Letters Patent of the United States, led February 16, 1885, Serial No.156,045. Said apparatus combines steam generating and superheating devices and means for subdividing oil and holding it thinly spread until vaporized by the heat einployed to superheat the steam, the superheated steam and vaporized oil being mingled with a suitable quantity of air and consumed at suitable burners with which the apparatus is provided. v

rlhe present invention consists in certain improvements in the means for generating steam, in the means for raising the vaporized oil to the mixingchamber, and in the means for supplying air to the mingled steam and vaporized oil, as we will now proceed to describe.

Of the accompanying drawings forming a part of this specication, Figure 1 represents a bottom view of our improved apparatus. Fig. 2 represents a longitudinal section of the same. Fig. 3 represents a section on line mx, Fig. 1. Fig. i represents a bottom view'of the steamsuperheating compartments. Fig. 'represents a section on line y y, Fig. 2. v

The same letters of reference indicate the same parts in all the Jdgures.

In the drawings, c represents the generator,

which consists of an oblong metal casing having in its lower portion the series of steamsuperheating compartments, p," communicating with each other by minute perforations b, through which steam passes untily it has passed through each compartment in succession. The steam enters the compartment p from the steam generating device hereinafterdescribed, and after passing through all the compartfments passes out through apertures c into spaces d d,extending partly around the cham- Iber e, which contains the oil supplying and 1vaporizing devices, and the combining-chamber e', which is separated from the chamber e 1by a perforated partition, f, the steam passing `into the said chamber e through orifices g.

h represents the pipe which receives oil from a reservoir), conducts it into the chamber e, and discharges it through a number of small perforations upon inclined diaphragms j j, of wire-gauze or other suitable material,which hold the oil thinly spread until it is vaporized by the heat applied by an external heater, lc, below the steam superheating compartments. The diaphragms j j are preferably inclined, as shown in Fig. 3, so as to permit the oil to llow downwardly from the pipe h, supplemental diaphragms ZZbeing provided below the diaphragmsjj to receive and spread the surplus oil dropping 'from the latter.

The construction thus far described is sub- -istantially the same as shown in the abovementioned application, and it therefore of itself forms no part of the present improvement.

In carrying out our invention we provide means for supplying steam independently to the oil-vaporizing apparatus, to lift the carbon of the vaporized oil more or less rapidly, and regulate the amount of carbon supplied to the flame resulting from the combustion of the mingled elements.V rlhe carbon,being heavier than air, naturally settles, and therefore has to be raised. We also provide improved devices for generating the steam supplied both to the superheating-com partments and the oil vaporizing apparatus.

Instead of holding the water which is to be converted into steam in tubes which are completely filled by the water, as in the apparatus above referred to, we pass it into generators composed of tubes or cylinders m, extending horizontally across the bottom of the casing a and over the heater k, so as to be heated thereby. Each cylinder contains, first, a central metal rod, 2; secondly, a roll, 3, of asbestus cloth wound closely around said rod 5 thirdly,

a covering of ne wire-gauze 4, surrou nding the asbestus, said parts about filling the interior ofthe cylinder m,- and, fourthly, a disk, 5,.of wire-gauze or other like material,placed across the delivery end of the cylinder. The central rod compels the water to circulate outwardly toward the surface of the cylinder, where the heat is greatest. rIhe asbestus cloth serves to hold the water in check, so that'it shall not pass through the cylinder too rapidly, and at the same time it spreads and -divides the water drops into minute parts, so that it may be more readily acted upon by the heat and more easily converted into steam, the wire-gauze serving to convey the heat to the saturated asbestus cloth, and also to receive into its interstices the generated steam and convey the same to the conducting-pipes, and the disk in the end serves to keep the steam under a slight pressure, giving evenness to the dow and exerting a backward force on the water, so asto prevent it from entering the cylinder too rapidly. In these cylinders7 or steam-generators, as we prefer to call them, the steamis formed as fast as the water is supplied, and a great advantage is realized in the spreading and dividing of tlie water, whereby a larger surface is presented to the heat than could be if the water were in an undivided body.

Any desirable number of generators m may be used, three being shown in the present instance, two of which are connected bya pipe,

a, and receive water from a reservoir or pipe, t, through a pipe, p, entering one generator, and deliver steam to the chamber e under the oil-pipe h through a pipe, o, connected to the other generator. The third generator is' connected by a pipe, r, with the reservoir, and supplies steam to the steam-superheating apparatus through a pipe, u, which enters the first compartment, p. The steam supplied to the chamber e by the pipe o carries the vaporized oil upwardly to the combining-'chamber e', the quantity of vapor raised depending on he quantity of steam supplied, so that by increasing or diminishing the quantity-of steam the height and intensity of the fiame can bev increased or diminished. rIhe pipes r and p are provided-with cocks @,whereby theamount of water supplied to the generators and the quantity of steam generated may be regulated.

We do not limit ourselves to the use of steam as the means for raising the vaporized oil. If desired, the pipe o may be connected to a blower or other air-forcing device, so as to introduce air into the chamber e, the air (which should be heated) serving the same purpose as the steam.

Our improvement in the means for mingling air with the steam and vaporized oil is as follows: We provide a series of delivery-tubes, c', in the top of the combining chamber, through which the steam and vaporized oil escape. a', which is wider than the casing, and is open at its under side, so that it will receive the' heated air rising from the external heater, 7c.

Said chamber has in its top an opening,

Over the casing a we place a chamber,"

through which pass tubes c from the combining-chamber e', said opening being wider than the tubes c', so as to permit the upward passage of air around said tubes into a chamber, d', above the chamber a. The top of the chamber d is pointed or of an inverted-V shape, and'has in each of its inclined sides a series of burners or openings, f. The heated currents of air ascending by the sides of the casing pass through a perforated partition, g', in the chamber a', and through the opening b into the chamber d', where they come into contact with the mixed gases which issue from the delivery-tubes c. The mingled gases and air-rising to the pointed roof of the chamber are thence spread in opposite directions toward the side openings, f. In this manner the air introduced into the chamber beneath is compelled to rise with the gases previously generated, having an escape only by the same openings through which those gases must pass; and as lthe oxygen thus supplied enters into chemical combination with the hydrogen and carbon generated in the main machine they rise together through the openings referred to into the open chamber, and when onceignited appear in'continuous flame. The advantage of this device 'for introducing air is'that it changes the character of the flame, takesaw'ay the smoke, and adds greatly to the heat. It can be used either with orwithwithout a chimney. The latter, however, serv/esto increase the force of the air-draft and adds proportionately to the heat of the flame'.

rlhe pipes r, which conduct water to the generators m, are preferably provided with bends p fr', which conduct the waterrst downlvwardly and then upwardly before it enters the generators, `thereby securinga uniform pressure of water in the generators, and subjecting the water to the action of the heater before it enters the generators, the bends being close to the heater.

VWe are aware that a steam-chamber surrounding the mixing-chamber is not new. We are also aware that a central core in 'a water-pipe to spread the water in a iilm about such core, and thus hold it n'earthe pipe, has been known. A
